The plot on the Scores Plot page indicates the similarity between samples.
Circles represent samples (which are linked to data files) as data points in this plot. Samples that lie physically near each other are similar. Both the x axis and y axis display principal components.
You can check the percentage values for the principal components. The labels on the x axis and y axis include the proportion of variance that the principal components add to the total variance as a percentage.
Point to a data point to view its coordinates, sample number, and replicate number.
